From a parts list the Arbor shows to have sealed bearings.

I have a 1970 Sears Craftsman Radial Arm Saw and needed some part or had a question. It appeared that Sears wanted to ReCall the Saw. I feel it was related to the Saw Running Toward Operators. The Saws can be dangerous and if I ever thought it would try to Run-Out, I started out and cut into the wood to prevent it from trying to Run-Out.

It is a very handy saw when doing a variety of woodwork (Framing or Finish).

Can you flip the belt so that it runs the proper way?

I do not have the radial arm saw, but on my table saw the belt runs directly from the pulley on the motor to the pulley on the arbor.

Have you in some way switched the polarity of the motor so it runs in the wrong direction?

If you are not familiar with electricity, you my take the motor to an electrical shop and have them look at it.

The motor and polarty are fine vs this saw has multi purposes and setups. To me the best use is framing a house as a Chop-Saw is better for framing IMO Today.

I enjoy my old equipment but not as much as I did when I did Small Jobs as Side-Line Work for Friends and Family vs "The Public". Interior Remodeling as Walls, Paneling and Cabinets. Lots of Prefabing and Installing vs hours at a Job site and fine finish work.

Volunteering with Habitat was a Good Match for me my first 5 years of retirement. Coming upon 20 years of retirement I try to keep up with most of our our needs in my range

Just to avoid possible confusion from a future reader; radial saw motors are all direct drive (no belt) and couldn't be mis-wired post production, and direction is designed to dig the blade into wood towards the table rather than lifting the wood into a user's face or chest.

Unfortunately, this wood digging effect does draw the trolley and blade forward and thick stock can be problematic. I imagine there has always also been the possibility that the trolley could break loose from or fall off the end of the arm with catastrophic effect. The liability led to the recalls and warnings. If you use one, you are on your own, like me.

Thanks for the added information and tips. The saw can be dangerous as almost any tool not to mention a failure on the saw. I can only remember loaning my saw out once and a small injury occurred. The saw has not been out w/o me since. Most friends that know I have the saw will come to me for wide cuts (as Prefab Counter Tops).

When I was active on Small Interior Remodeling Jobs I added wheel to the back of the table (that allowed me to lay the saw in my utility trailer to travel). My Chop-Saw that I added in 1984 became the framing Workhorse for Metalworking, Woodworking and Carpentry. I have a few tools that might qualify as antiques. As my (small) 200 lbs Lincoln Arc Welder (from the 1940s I believe with a copper core and no cooling fan.
